Garage floor paint/epoxy

[Daria B.]

Hi- The garage floor has seen better days. It’s never been painted and has over the years had oil and likely gas spills. The area is 220 sq ft (just a 1 car) and from what I see in 1 gallon cans will more than cover the area. Question is what to get. Amazon has this in slate grey for $36.92. “KILZ L377711 1-Part Epoxy Acrylic Interior/Exterior Concrete & Garage Floor Paint, Satin, Slate Gray, 1 gallon” I looked at several options but does someone have a recommendation on proven use off a product with good results? Given the condition I would ideally like to get something as a once over without having to scrub and clean the floor. You know, just cover it up. I am also looking to paint the walls and ceiling. It too has never been done. Thanks BPers
